An in-depth study into shipping’s future energy profile suggests only half of the world’s fleet will be burning petroleum-based fossil fuels by 2050, helping to achieve a significant improvement in the industry’s carbon footprint.

In the recently released study “Energy Transition Outlook — Maritime”, classification society DNV GL is forecasting that only 50% of the deepsea fleet will be powered by heavy fuel oil or marine gas oil by the mid point of this century, while 32% of the fleet will opt for LNG and 18% for biofuel.
